Lubricant particles, method of preparation, and photographic elements

Abstract

This invention contemplates droplets of liquid lubricant, each droplet coated with colloidal particulate suspension stabilizing agent. The invention also contemplates a method of making size stable lubricant droplets by forming a discontinuous phase of lubricant droplets in a continuous aqueous phase containing a particulate suspension stabilizing agent, reducing the size of the lubricant droplets and limiting the coalescence of the lubricant droplets by action of the particulate suspension stabilizing agent. A third aspect of the invention is an imaging element comprising a support, at least one light-sensitive layer and a protective layer further removed from the support than the light-sensitive layer, at least one layer containing droplets of lubricant coated with colloidal particulate suspension stabilizing agent.
